These methods are only to help you distinguish between a Witch and a true Healer. It is NOT to be practiced what so ever.
Before a Witch may act upon this method, he stays dirty and away from water for more than 40 days. After that, the Witch may enter a dark room, light a fire and smoke incense of good or bad odor, according to the subject of the request. If, for instance, the Witch intends to separate or stir up hatred and enmity between people, he would put bad-smelling incense onto the fire. But if he wants to bring love between people or neutralize the Witchcraft of an impotent person or Witchcraft in general, he would put a nice-smelling incense onto the fire. Afterwards, he may start reading his spells using specific incantations. These would contain the Witch’s oath to the Demon Chief and seeking refuge in him.
After the incantations, a phantom appears before him in the form of a dog, a snake, etc. Then the Witch would command it to do whatever he wishes. Sometimes nothing appears before the Witch, at others the Witch may hear a voice or nothing at all. In this Case, he may put a knot around the trace of the targeted person such as a lock of his hair, a sweaty piece of his garment etc., and then he would instruct the Demon to obey whatever he should command.
